f10 all whom 'iz' may concern:

Beit known that I, AUGUs'r L. BEAUPAIN, residing at Springfield, in thecounty of Clark and State of Ohio, have invented certain new and usefulImprovements in Printers EX- tension Furniture, of which the followingis a speciiication.

rlhis invention relates to certain new and useful improvements inadjustable blanking out material or furniture for printers use, and theinvention comprises a pair of sliding members which carry a plainlymarked scale, and means for securing and firmly locking the extensibleor sliding sections in place at any desired position.

Another object of the invention is to provide a strong, simple and.efiicient adjustable metal furniture for printers use and for otherpurposes to which it might be applied, to accomplish with one piece theresult heretofore obtained by the combination of numer-ous smail rigidpieces, and further to insure a perfectly tlat and even Working surface,which is not always obtainable with a number ot small pieces.

A further object of my invention is to provide a scale, with plainlyvisible graduations that will enable the user to quickly and accuratelyadjust the device to any desired length and to render unnecessary thegreat assortment ol stationary lengths now commonly used in practice,and thus reduce to a minimum the time consumed in obtaining any desiredlength, and economizing in room required ior storage as well aseliminating the sorting and returning to their proper places of manypieces.

My invention also includes those novel details of construction,combination and arrangement of parts, all of which will be firstdescribed in detail, then be specifically pointed out in the appendedclaims, and illustrated in the accompanying drawings, in which Figure 1,is a perspective view of my inven tion. 2, is atop plan view thereof.Fig. 3, is an end view looking in the direction of the arrow in Fig. 1.Fig. 1, is a cross section on the line ln-4 of Fig. 2. Fig. 5, is asimilar view on the line 5-5 of Fig. 2. Fig. 6, is a central verticallongitudinal section on the line 6"-6 of Fig. 4. Fig. 7, is a horizontalsection on the line 7 7 of Fig. 4. Figs. 8, 9 and 10, are detail crosssections of modiiied forms oi my invention. Fig. 11, is a detail viewoi' a slightly modified form of the corrugated member.

Referring now to the accompanying drawings, in which like letters andnumerals of reference indicate like parts in all of the igures, 1represents one of the slidable sections and 2 indicates the otherslidable section.

The sections 1 and 2 each have a head lil-2@L respectively, and thesection 1 is provided with an outer beam member 1b and an intermediatebeam member 1C, while the section 2 is similarly provided with an outerbeam 2b and an inner beam 2C to cooperate with those lb-lc of thesection 1.

The beams 11)-10 of the section 1 have side plates 11i-1y respectivelywhose adjacent edges are grooved as at 1Z to form a T- slot 1W betweenthe side plates lx-ly to receive the side plates 2y of the intermediatebeams 2C of the section 2, and the section 2 is correspondingly providedwith a slot 2W for a similar purpose to that of the slot 1W. The sideplates 2y are of such shape in cross section as to conform to that ofthe T-slot 1w and have a sliding movement therein. The intermediate beam1c of the section 1 also has its side plates 1y provided with flanges toform grooves 1r to cooperate with the flanges 2f oi' the section 2.

The inner wall of the beam 1b carries a tongue 1 d of T -shape in crosssection to enter the T-groove 2e of the beam 2C, while the beam 2b has atongue 2d, T-shaped in cross section to enter the T-groove 1e on theouter wall of the beam 1, as clearly shown in Fig. 4, of the drawings.

From the foregoing it will be seen that the interengaged sections 1 and2 are rigidly united (to interlock the same and thus prevent lateralmovement of the sections) While at the same time they may be endwiseeXtensible and in order that they may be locked in their extendedpositions the inner face of the beam 1C of the section 1 is serrated asat 1s while the corresponding tace of the beam 2b is likewise serratedas at 2s to cooperate with a rod 3 that passes through the end head 2aand through a bridge plate 2g secured to the beam 2b in any approvedmanner at the end farthest from the head 2. The rod 3 also passesthrough a bridge plate 1g secured to the beam 1C in any approved mannerat its end farthest from the head 1.

A washer 3 i is riveted, or otherwise secured to the end of the rod 3 toprevent endwise movement thereof in one direction, while washer 3bwithin the socket 2n of the head 2et performs a like function to preventthe rod being endwise moved in an opposite direction.

The rod 3 has wings 80 to cooperate with the serrations 1S and 2S toloci-1 the sections 1 and 2 from endwise movement. 1t is to be notedthat the wings 3C are of substantially circular plate-like formeccentrically arranged with respect to the longitudinal axis of the rod3, so that whei'i the rod 3 is in one position the wings 3C will be outof register with the serrations 1s and 2S respectively and when turnedinto another position such wings 3C will be in engagement with the-fixed serra- 'tions andlock the sections together.

The socket 2m of the head 2a, it is to be noted, is of two bores, theouter bore 2 of which is of greater diameter than the inner bore toreceive the portion 1m of greatest "diameter of the key plate 1, whoseportion l of lesser diameter enters the portion of lesser diameter ofthe socket 2n, see Fig. 6, of the drawings.

The rod 3 has its outer end slotted as at 3d to receive the plate 4, asshown, and the socket 2In is provided with a pair of radial slots 2p toreceive the portion 2m of greatest diameter of the key plate 4 when theparts are in their locking position. The hey plate 4 is slotted as at 1Xso as to be endwise movable within the slot 3d of the rod 3 andprojected with its finger engaging bar ly within the plane of the outerface of the end 2a so as Ato lie flush therewith, as indicated in Fig.1, of the drawings.

When my improved furniture is to be formed of sheet metal, the sheetmetal portions may be corrugated, as indicated in Fig. 11, to give thesame the required strength.

Instead of forming the grooves 1v-2W of T-shape in cross section theymay be of V- shape in cross section, as shown in Fig. 8, of thedrawings, and the cooperating end bars of the opposite member may beformed of corresponding shape in cross section to cooperate therewith,as shown in Fig. 8.

Instead of making the grooves 1-2', as shown in Figs. 1, 2 and 8, theymay be formed of a cross sectional shape, such as is shown in Figs. 9and 10 of the drawings, and the corresponding bars of the oppositemember may be correspondingly formed to cooperate therewith. Also thebars 1d and grooves 2e may be in cross section of a dovetail shape, asshown in Fig. 8, in lieu of the sectional formation shown in the formdisclosed in Fig. 1 of the drawings, and l do not desire to com'inemyself to any particular shape of groove 1W-2W, or 10-2e, as variousmodifications of the cross sectional shape may be made while stillmaintaining the principal objects of construction of my improvedfurniture.

One ofthe sections 1. or 2 (the section 1, is

shown in the drawings) is provided with a series of plainly visiblegraduations sub-divided to correspond to the serrations 15-2s and thescale is divided to read from a predetermined amount up to the limit ofits extension. For instance, if the furniture when in its closedposition is 22 picas long the scale should read from 22 up, as shown onthe drawings.

ln the practical application of my invention, if a furniture 2911,4picas long is desired, for example, the operator grasps the fingerengaging member ey, pulls the winged plate l out to the position shownin Fig. 6, and turns the rod 3 until the wings 8C thereof are out ofregister with the sei-rations 2S-1S and extends the sections 1 and 2until the 295A division is in alinement with the edge of the oppositesection, as shown in Fig. 1, of the drawings, after which the rod 3 isgiven a turn until the wings 3C can enter the serrations 1S-2S and thusprevent endwise movement of the sections 1 and 3, thereby holding themat the proper position and in order to lock the rod 3 and thereby lockthe sections 1 and 2, the`operator then passes the winged plate 4 bachinto the socket 2n with the portion 1m of the winged member in the slots2p of the head 2, as shown in Fig. 1 of the drawings. -The furniture maybe then used for a space 2Q-1- picas long.

V-While lhave shown the scale graduated up to a certain number on thedrawings, l desire it understood that the number of divisions on thescale will depend largely on the length of the furniture used and theamount of extension permitted between the two sections of the device,and l do not desire to limit myself to the exact graduations, indicatedon the drawings.

The interengaged side plates 1X-1Y--2X-2y by virtue of theirinterengagement, prevent lateral movement of the sections 1 and 2respectively, thus interlocking such sections 1 and 2, as it were, fromlateral movement. The supplemental tongue and groove connection 1d2dassists in more fully performing this function and also in rendering thedevice more rigid.

From the foregoing it will be seen that 1 have provided a very simpleand effective construction of printers blanking out material, commonlyknown as furniture, wherein a rigid connection of the two extensiblemembers is maintained and wherein means are provided for securelylocking the device when set to the desired length. 1t4 will be also seenthat l have provided a scale in a position that can be easily andquickly read and that by forming the serrations 1s and 2s and providingthe rod 8 with theV wing-like membersC they will serve to clean out anydirt that may accumulate in theserrations and thus insure absoluteaccuracy in obtaining the desired adjustment ofthe device.

In the practical manufacture of my device, as before stated, it may bemade in any desired length and of any desired width and height and 1 donot conne myself to the exact proportions shown on the drawings, nor do1 confine myself to the speci'c details shown in the drawings, asnumerous changes inthe details of construction and arrangement of partsmay be made without departing from the spirit of the invention, or thescope of the appended claims.
